Welcome and thank you for giving me the opportunity to assist you with your tax question.
EBITDA is an acronym for Earnings Before Interest, Taxes, Depreciation, and
Amortization. It is a good beginning point to measure a company's potential value, and essentially it involves subtracting expenses from revenue EXCLUDING interest, taxes, depreciation and amortization. The resulting number gives a basic picture of the company's profitability as well as its ability to pay off what it owes.
It is worth mentioning that EBITDA does not conform to general accepting accounting principles, and therefore, adjustments can be made.
As to your first question, 3 or 4 times EBITDA is 3 or 4 times the resulting
number from the above formula.
As to your second question, amortization is excluded from the EBITDA.
As to your third question, I believe the answer is explained above.
